英文小作文：

When dealing with a tooth with a severe infection, endodontic treatment is often necessary to save the tooth and prevent further damage to the surrounding tissues and structures. However, this type of treatment can be a painful process, which requires careful planning and post-operative care to ensure a successful outcome. The access cavity is made to allow access to the infected root canal, and once the canal is cleaned and filled, the tooth can be restored with a crown or other type of restoration to improve its function and appearance. The patient should follow post-operative care instructions to avoid infection and ensure that the tooth heals properly. This type of treatment can be a valuable asset in saving teeth with severe infections, but it requires patience and understanding from the patient.
